I have a Peplink Balance 20 (Hardware Version 1) which, after a manual reset (>10 seconds hold and the status red light has gone from flashing to unlit), releases its configured IP address and admin password to the default. When I then make any changes via the webpage administration interface at 192.168.1.1, including ‘Restore Factory Settings’, and save them, I receive a confirmation that they have been saved but they are not enacted when I power down the router. I opened the router and replaced the battery, but changes still are not present after a power-down. Does anyone have any idea as to what I should do next? Thank you in advance!
